Once you have downloaded the Packet Tracer template network, please save this and create a working copy. At every stage, from basic configuration to completing each task – the advice of the module team is to save a new version of your Packet Tracer file. If you create any errors, have any system issues etc, you will be able to recover or roll back to a previous state with ease.
Also, you must regularly save your configurations on each device within Packet Tracer, the quickest command to accomplish this is the ‘wr’ command short-cut, which can be applied to routers and switches equally.
The base topology, used in your network will resemble the following network structure seen in figure one. This is the same system used in many Cisco academies.
Figure 1 Cisco common virtual day school network topology interfaces
From this, everyone will see:
- two routers
- two switches
- various crossover and straight Ethernet cables as required
- at least two ‘simulated’ PCs
In keeping with the challenge nature, of the TM257 network, the module team have made a single noticeable modification to the topology, removing the two cross-over cables between S1 and S2. As a student taking this EMA, please do not add or remove any cables or devices. You can see in Figure two, your modified topology and the names of each of the devices in your new structure.
Figure 2 TM257 virtual day school named network topology
The table below, describes in greater detail the above image and the cabling structure in operation on your Packet Tracer file.
|From Device||To Device||Cable/Connector|
|Newton (was R1)||Einstein (was R2)||Crossover cable, from Gi0/0/0 to Gi0/0/0 or equivalent interface|
|Newton||Heisenberg (was S1)||Straight cable, from Gi0/0/1 (or equivalent) to Fa0/5|
|Einstein||Schrodinger (was S2)||Straight cable, from Gi0/0/1 (or equivalent) to Fa0/5|
|PC0 (was PC-A)||Heisenberg||Straight cable to Fa0/6|
|PC1 (was PC-B)||Schrodinger||Straight cable to Fa0/18|
On Packet Tracer you can show interface identifiers within preferences or hover over the end of a cable with your mouse to see each of the connections.
You will also need to enter a series of basic interface commands to ensure that your Packet Tracer network has the correct basic configuration. We are asking you to do this, as this is an essential part of the face-to-face day school, you are repeating this as part of the virtual day school experience. Read with care and enter these commands as shown. Do not enter any additional commands or enable any router or switch security features. While they are important, during the day school they may impede your likelihood of success.
Please enter these with care on the correct devices, also remember to ‘wr’ and also save your Packet Tracer file. The basic configuration is a set of interface commands that will bring each device ‘up’ and allow you to build your solution network. There will be no marks for this part of the virtual day school.
